ITOB 411 Error

[Former Member]

Does anyone know how to work around ITOB 411 error message? 'Serial number xxxxxx for material xxx could not be read.'

We are creating 60 serial numbers as we add them to existing contract document line items using modules SERNR_ADD_TO_AU and SERIAL_LISTE_POST_AU. This is successful. The Program waits for up to 8 seconds, then uses ITOB_SERIALNO_READ_SINGLE to retrieve the ITOB structure for each serial number that was added, in order to modify the last goods movement date. When the read is successful, ITOB_SERIALNO_MODIFY_SINGLE is used to successfully modify the LGMD. The first 15 serials are read and updated successfully. The error comes usually on about the 16th attempt of calling ITOB_SERIALNO_READ_SINGLE and stops the processing. Using various modules such as GET_SERNOS_OF_DOCUMENT verifies the serial number in the error message is in fact created. Any information is appreciated.

When we have quantities of 15 or below, there are no issues.

Below is an excerpt of the code used.

Hi,

Try to clear the buffers , there is an SAP note on this . I've searched but could not find.

Hi,

Looking at your code, you are using two different variables while calling the below two FM's.

Most probably the values of the materials here are different.

CALL FUNCTION 'SERNR_ADD_TO_AU'
material = ls_out_items-material

CALL FUNCTION 'ITOB_SERIALNO_READ_SINGLE'
i_matnr = ls_order_item_in-material

During debugging, check if the values are the same. Including the preceeding zeros.

Regards,

Jovito.
